Abstract EN
Background.
Polysaccharide of Spirulina platensis (PSP) is a kind of water-soluble polysaccharide extracted from Spirulina platensis.
It has been proved to have antitumor, antioxidation, antiaging, and antivirus properties.
And it has a promising prospect for wide application.
Objective.
This study aims to identify an extraction process for high-purity polysaccharide in Spirulina (PSP) through a series of optimization methods and then evaluates its initial antiaging activities.
Methods.
Four kinds of extraction methods—hot-water extraction, alkali extraction, ultrasonic-assisted extraction, and freeze-thaw extraction—were compared to find the optimal one, which was further optimized by response surface methodology.
PSP was obtained after the crude PSP was deproteinized and depigmented.
The antiaging effects of PSP were preliminarily evaluated through in vitro cell experiments.
Results.
The alkali extraction method was determined as the optimal method, with the optimized extraction process consisting of a solid-liquid ratio of 1 : 50, a pH value of 10.25, a temperature of 89.24°C, and a time of 9.99 h.
The final PSP contained 71.65% of polysaccharide and 8.54% of protein.
At a concentration of 50 μg/mL, PSP exerted a significant promoting effect on the proliferation and traumatic fusion of human immortalized epidermal cells HaCaT.
Conclusion.
An extraction method for high-purity PSP with a high extraction rate was established, and in vitro results suggest antioxidation and antiaging activities.
